• 6009 USB appears in the devices, but no measurement and Automation Explorer Manager

  I have a NI USB 6009, which is visible through Windows, but not in MAX.  Uses OR-DAQmx 9.0.2 (so it should date back to before the question HID/PID, I've read).  See the attached screenshots.

  I suspect I'm missing something.  What?

  Sounds like a classic MAX database corruption.

  There are methods to go through and fix it... they are quite complex and convoluted.  More simple is to uninstall/reinstall just MAX.  Your version of some 9.4.0f1 with the Windows XP hotfix versions works well for this same problem on several machines here, looks like out for download 9.5 now.

• Color Laser Jet MFP M177fw Pro: Printer is not recognized by the devices.

  When connected to a computer via the usb - B to usb at the back of the device connection, computers do not get a signal telling them that they are connected to anything. The computer windows 7 behaves as there is nothing plugged and a Mac running 10.9.5 simply gives the error message "the disk you inserted is not readable by this computer. When I try to download the drivers for the device manually, the installation of HP can't find the printer in the devices, even when it is plugged. Both computers have been restarted, several cables (who work for other printers and are located in the length of HP limit) are the same exact behavior.

  Solution has been found, windows 7 update, but a driver do not go along, while some things have worked when it is plugged. HP partner, effects no side windows just weird.

  For those who read this topic after googling their problems: updated all the drivers. EACH OF THEM.

• Can't see printer to the Printers folder & devices

  I do not see my HP 6 p printer in the devices folder & printers but it shows in all applications when you print.  I had it installed & tried to uninstall so now it is not visible, but apparently the driver still exists somewhere.  How can I find the driver and remove it so I can reinstall the printer properly

  most likely the printer is correctly installed.  If the parallel port is configured in the BIOS of the machine as the printer SPP is classified as part of the machine.  Right click on computer you.  If one of the options of the menu's properties of the printer which is where it's at.  You can configure the BIOS of the machine to the EPP.  I think that it will work with this device.

• USB printer not detected on satellite series?

  Hello

  Have a laptop Toshiba Equium and today I bought a printer from a different manufacture.
  USB cable is not supplied with the printer (not good things) and so had to buy a.

  Laptop does not accept the USB cable saying something like USB isn't signwritten with the laptop?
  I have no idea what has happened?

  I'm sure that the printer is 100% and the USB's all nine... the majority of the facility took place until this problem is with the USB
  The laptop never had a printer connected before in 18 months of ownership.

  Any help!

  Thank you

  Hello

  First of all, you must make sure that you bought a straight cable and which is compatible with the laptop.
  My sister uses a USB printer and the cable that she bought looks like this;

  [USB 2.0 printer cable | http://images.tigerdirect.com/skuimages/large/C184-4000_U_6-main.jpg]

  But the note man; You should check this printer installation instructions.
  Sometimes the driver (shipped with the printer) must be installed before you connect the printer to the computer!

  What you could do to first remove the USB ports, controllers from Device Manager and reboot the laptop.
  After restarting again the USB ports must be installed again.

  After this short stage, you continue with the installation of the printer described in the manual!

• OfficeJet 7310 all-in-One: the device is not complete - Officejet 7310

  Initially, a 10 on my network windows desktop could no longer communicate with my Officejet 7310 all-in-one ethernet connection.  The Office recognizes the 7310 as a printer, but not as an all-in-one.  I tried to reinstall the software using the prescribed protocols, without success. I decided to ignore the problem.  The Office could still use the 7310 as a printer, but not as an all-in-one. In addition, my two laptops could always use the all-in-one features.

  Today, no reason apparent, the all-in-one feature has stopped working on my windows of 10 laptops.  When I tried to scan a document, I received a message that says: "device to complete installation. Attach the usb cable or reinstall the software. "I am more able to reinstall the all-in-one software.  Just like with my office, my laptop can use the all-in-one printing function, but cannot use the functions of HP Solutions Center.

  I used the protocols recommended - uninstall the 7310, running windows disk cleanup, run ccleaner registery cleaner, closing all devices on the network except the 7310 and a laptop.  Nothing works, despite several attempts on various computers.  Is no longer, I can install the software of HP Solutions Center on any of my windows 10, 64-bit, PCs - wired or wireless.  The 7310 is essentially a 'brick', because it no longer works as an all-in-one.

  What can I do to fix this? Help.

  Hey @fatz2fly,

  I don't think that you have missed something, but I recommend you uninstall a more holistic approach at this stage. I know that this appears at first sight very complicated, but I burst in instructions step by step to make it easy to follow

  1. Hold down the Windows Logo key on the keyboard and the 'R' to open the dialog box run, type % temp %
     • Delete all files and folders in the temp folder. Choose Skip if all pop ups seem to say all files cannot be deleted
  2. Delete the printer devices and printers and the driver from the properties of the server. See the instructions below before proceeding to step 3.
  3. Download the software and choose Save as, save to desktop >AIO_CDB_Net_Full_Win_WW_130_141.exe
     • After downloading software and extracts, reopen the temp folder, use the instructions in step 1.
     • Locate and open the folder starting with 7z (example: 7zS2356)
     • Open the Util folder
     • The CCC folder
     • If you have a computer HP run the L3uninstall.exe. If you have acomputer no HP run the L4uninstall.exe
  4. Once the uninstall is complete, reboot the computer
  5. Download and run CCleaner - How to use CCleaner.

     Installing software on the computer with a registry key, its place would be like trying to paint a wall with a hole in it, you need to patch the hole first. Repair the registry, and then install the software. Registry cleaners can be useful tools to solve certain types of problems in the registry, as those that are created when a program does not properly uninstall or a malware infection is not cleaned properly.

     This suggestion is not a document of HP, it is my own opinion. My preference is CCleaner, I use it on my computers. If you have a registry cleaner already, or that you prefer, you can use it.

• Follow these steps to reset the registry settings and options for Windows Installer.
  • Hold down the key of the Windows Logo on the keyboard and the 'R' to open the dialog box run
  • In the Open box, type msiexec /Unregister, and then click OK.
  • Hold down the key of the Windows Logo on the keyboard and the 'R' to open the dialog box run
  • In the Open box, type msiexec/regserver, and then click OK

* Note: there is a space between the c and the /.

If you do not at this stage, use this link to perform another way. Restart Windows install

1. Run the system Accessories\ tool disk cleanup <> How to delete files using disk cleanup
2. Download and install the latest version of Adobe flash player http://www.adobe.com/support/flashplayer/downloads.html
3. Restart the computer
4. Download and run the HP printer install wizard for Windows
5. The HP printer for window installation wizard was created to help Windows 7, 8, 8.1 and 10 users download and install the most recent and most appropriate HP software solution for their HP printer.

Please let me know if that solves the problem, or if you need assistance. Thank you!

• Will not print with the exception of the test pages

  I can't print any document (PDF or Word format) but all the test pages will be printed. The document will show less than a second in the print window then disappears. It doesn't matter if I try to print wireless or I plug the USB printer on the computer.  Also, no Google Cloud Print will print.

  The printer is a Photosmart C7280 all-in-one and computer is a HP Compaq nx7400. I use an operating system of Windows 7 with Office 2007.

  Welcome to the joalrabr forums,

  I understand your Photosmart C7280 print not since your connected PC or wireless USB however, it will print the pages of the test directly from the printer itself.

  First of all, I would like to run the HP print and Scan Doctor. I hope the tool will fix the problem. If it cannot, it will tell you the problem.

  Please let me know the results!

  Happy Monday

• Double-sided printing. The different margins top, front and back

  I'm tying to print the aWord 2013 document on A4 sheet, double-sided, on my envy of 7640, now my Windows 10 pc.

  I played with different sizes of margin and sometimes the text at the top of the page is missing or text starts at least 30 mm from the top of the cover page. Still back starts about 7-8mm from the top of the printed page.

  I can't say with certainty that it is since the free update of Windows 10, but he printed double-sided OK in the past.

  I have not modified parameters, only diversity of margin sizes when creating documents.

  Hi @crag67,

  I understand that when you print from 2013 of Word by using the duplex function, the margins on the front of the page and the back of the page are different. This happens when you print from other programs or just the word? If it occurs with other programs, it could be the driver, but if it occurs only when you print from Word, Word or a framework within the program, in which case I suggest reaching out to Microsoft or the Microsoft community.

  If this problem occurs when you print from several programs, we will remove the driver and re - add new.

  I suggest to use the following steps to remove the printer from the device and printers and the driver from the properties of the server.

   

• Connect USB printer to E4200

  Hello

  I think I discovered that you cannot currently connect a usb printer to the usb port on the e4200 to share it on the network.

  However I have heard that this could be facilitated reports may be activated in the spring.

  I've also heard of "virtual usb", but I don't know if this has anything to do with it.

  Anyone can shed some light on this?

  Receive word of USB print support will build on the next firmware update. Until then, we'll just have to wait.

• Unable to print from the Mac Book Air (OS 10.9.2) on HP Envy 5532

  Hello

  I just bought a new HP Envy 5532 printer but cannot print to the device? (Wireless)

  When I add the printer using 'System of preferences, Printers & Scanners etc', I get the following message:

  "Unable to verify the printer on your network" unable to connect to 192.168.1.116 due to an error. You want to create the printer?

  If I click on continue, he adds the printer ok, however, if I try and use it, work just sits in the print queue without actually printing.

  I am able to ping and connect to the printer using http. I am almost able to scan a document so that it is directly connected via http, however, once a doc has been scanned, I am unable to 'download' or see it in reality.

  It seems that network connectivity is fine, however, as I still can't really complete all print jobs.

  Any suggestions would be welcome.

  Thank you

  Hi JMatt100,

  Welcome to the HP forums!

  I see your message you have a craving 5532 that doesn't seem to connect with your Mac running 10.9. I'm sorry to hear what is happening, but I will certainly do my best to help!

  I recommend that you try power cycling your network, with the printer and the Mac. To do this, please turn the printer and the Mac off and wait until they close completely. Then pull the power cord on the router for 30 seconds. Once the router is plugged in please wait for all the lights to return to normal before you turn on the printer and the Mac back on. Once it's done see if Mac acts differently when you try to connect with envy.

  If the problem persists, I would you reset your printing system (do not add the printer back immediately), and then perform a check/repair your disk permissions. Once these full please download software HP for your printer and see if you can get things working properly using the HP software.

  I hope hear from you soon!
